Hydraulic power booster using two pistons in fluid housing

摘要

The pistons (2,3) bear on one another or on the housing (1) via one or more springs (7) and are joined to the housing by diaphragms (5,6) so as to close the fluid off within the housing. The two pistons lie in parallel and the housing can be coupled to a frame (10) by means of a device (8,9). The interior (4) of the housing is split into two chambers which are interconnected by a pressure-limiting or switchable valve. The first piston (2) terminates in the first chamber and the second piston (3) in the second chamber of the housing. The output end of the pusher is connected to the first piston and the pusher entrains the housing until the force at the output or the position of the housing is reached at which the housing is supported on the frame. The pusher design is installed in a magnet for power boosting.
